- Spanish Version: [SilentBoot]
This feature allows to suppress all output from RouterBOARD over serial port and suppress beeping on RouterOS boot. Very useful if you have some custom devices attached to it and they get confused from output when router boots up or is operational.
To have this feature you have to have corresponding RouterOS version or newer and correct RouterBOOT version or newer running on RouterBOARD hardware.

To disable console output you have disable console on serial output, that is enabled on all RouterBOARD devices by default. That can be achieved this menu:
by default you will see this output in the menu:
[firstname.lastname@example.org] /system console> print detail Flags: X - disabled, U - used, F - free 0 F port=serial0 term="vt102"
Then just disable that entry there.
Other part of configuration that will work only on RouterOS 4.4 or newer and RouterBOOT 2.25 or newer To suppress boot messages, you have two different ways to do same thing:
/system routerboard settings set baud-rate=off
- When RouterBOARD starts to boot press key as specified by message
Default message looks like that:

- Select option:
